Very good beautiful packaging and accessories expect the tips.

Build Quality:

Cable kinda reminds me of the jvc fxc50

cable except thicker

the glue use on the housing was really poor as I was able to remove it in mere minutes without the use of any tools.

The glue problem worries me but even the re0 and head direct has glue issues.

Initially I did not like this earphone. The bass was over powering most of the spectrum like a sub woofer in my head.

and the treble was very rolled off. But the bass was impressive for an IEM some of the lowest bass I've ever heard from an IEM. I dare say that the bass extension is better than that of several full size headphones I've tried.

I ended up dampening the back of the housing with some blutak(I also think the used a softer plastic for the housing because a rigid housing would had created much worst backwave and muddy the bass alot more.)

The MR2 is a bass heavy IEM with a okay midrange and slightly rolled off treble which opens up

with burn in.. The details were imnpressive it seem to be able to keep up with my jvc fxc50 in that aspect. After significant burn in the bass settles down for more of balanced sound. The lowering of the bass does reveal more of the mids and slightly more highs.

I believe that they do fit in to the $50 bracket with very pleasant warm sound, but do feel that they lack extension in the highs. Detail slightly below that of the budget buster around it's price point, but does provide a sound signature that is very different. The extra low extension of the bass makes it feel more like a fullsize headphone rather than an IEM, but build quality concerns me.

I highly recommend opening up the back housing and blutacking the back housing

personally I've grown to like them after adding 2 layers of electrical tape followed by a layer of nutty putty(blutak alternative) and 2 layers of painters tape.(this tightens up the bass and gives in a better bass slam)

I retract my reccomendation for bluetak after 6 months these have grown on me but I had stuff way too much bluetack and have snagged a voice coil wire and killed and driver in the process.

Enjoying my pair with the Shure E2 Black Sleeve with the 4mm exit bore ATM Earsonics SM3 eartip ATM, gives the best balance of isolation, comfort and sound for me.

I must say, I'm impressed (but then again, I'm easily impressed)

Its small, disappears in your ears easily, synergizes with the Fuze very nicely, and its wonderfully balanced (slightly forward sounding mids, similar in level to the SRH840 somewhat). On the contrary to what Nagasaki said, I don't think they're muddy at all. While the bass are the focus of the MR2, I don't think the treble takes as much as a backseat as the SE215 (with Shure Olives).

It reminds me of the PL50, but its not as forward sounding nor is it as aggressive. To say the least, its a very polite sounding earphone with quite a spacious sound.Technical parallels can be drawn with the Brainwavs M1 at the moment, but I'll reserve more comparisons and whatnot post a break-in period. So far though, I believe that the PL50 should be more technically capable than the MR2 Pro.

The MR2 Pro sound very well balanced to me, and while the bass is the primary focus of the earphone (has quite a bit of rumble presence on it), the other frequencies don't sound lacking. The mids, while forward, are rather dry, and the treble doesn't sound offensive in any way, making listening to the earphones easy =)

Faults with the earphone so far would lie in its driver flex, and while its soundstage has decent depth, its width is pretty average, I haven't tested for height yet with my games however. Instrumental separation is decent, but could be better overall. It'd also be nice if the earphone came with a neck slider, lotsa spare space between the chin and the Y-splitter there =O

One thing I do wish for though, is for the lower bass levels of the earphone to be slightly quieter so as to give the earphone better 'black values' (contrast). <- Fixed with the SM3 Eartips, not so much of a rumble now compared to plain presence, trebles got slightly tamed though, mids stand out better, and aren't as dry.

Just gotta say that while its not as technically capable as the Klipsch Custom 3, I enjoy the MR2 thus far better than the KC3 due to its more engaging sound sig and ease of use =)

From a frequency sweep, they seem to be accented a little at the 8-10kHz mark, and rolls of gently from the 12kHz mark all the way till the 17kHz mark. 18kHz is audible with highly increased volume levels, but the 19 and 20kHz levels are pretty much black (my hearing is still effective up to 19kHz)

More to come after breaking the earphone in =)

PS: One severe caveat of the earphone seems to be its driver flex. Lotsa crackling =O
